Eric W. Biederman authored
While reviewing the code of umount_tree I realized that when we append to a preexisting unmounted list we do not change pprev of the former first item in the list. Which means later in namespace_unlock hlist_del_init(&mnt->mnt_hash) on the former first item of the list will stomp unmounted.first leaving it set to some random mount point which we are likely to free soon. This isn't likely to hit, but if it does I don't know how anyone could track it down. [ This happened because we don't have all the same operations for hlist's as we do for normal doubly-linked lists. In particular, list_splice() is easy on our standard doubly-linked lists, while hlist_splice() doesn't exist and needs both start/end entries of the hlist. And commit 38129a13 incorrectly open-coded that missing hlist_splice(). We should think about making these kinds of "mindless" conversions easier to get right by adding the missing hlist helpers - Linus ] Fixes: 38129a13 switch mnt_hash to hlist Cc: stable@vger.kernel.org Signed-off-by:

Commit bc96f648 (xen-netback: make feature-rx-notify mandatory) incorrectly assumed that there were no frontends in use that did not support this feature. But the frontend driver in MiniOS does not and since this is used by (qemu) stubdoms, these stopped working. Netback sort of works as-is in this mode except: - If there are no Rx requests and the internal Rx queue fills, only the drain timeout will wake the thread. The default drain timeout of 10 s would give unacceptable pauses. - If an Rx stall was detected and the internal Rx queue is drained, then the Rx thread would never wake. Handle these two cases (when feature-rx-notify is disabled) by: - Reducing the drain timeout to 30 ms. - Disabling Rx stall detection. Reported-by:

Load balancing can be triggered in the critical sections protected by srmmu_context_spinlock in destroy_context() and switch_mm() and can hang the cpu waiting for the rq lock of another cpu that in turn has called switch_mm hangning on srmmu_context_spinlock leading to deadlock. So, disable interrupt while taking srmmu_context_spinlock in destroy_context() and switch_mm() so we don't deadlock.

Jesse Gross authored
Currently, searching for a socket to add a reference to is not synchronized with deletion of sockets. This can result in use after free if there is another operation that is removing a socket at the same time. Solving this requires both holding the appropriate lock and checking the refcount to ensure that it has not already hit zero.

Each mmap Netlink frame contains a status field which indicates whether the frame is unused, reserved, contains data or needs to be skipped. Both loads and stores may not be reordeded and must complete before the status field is changed and another CPU might pick up the frame for use. Use an smp_mb() to cover needs of both types of callers to netlink_set_status(), callers which have been reading data frame from the frame, and callers which have been filling or releasing and thus writing to the frame. - Example code path requiring a smp_rmb(): memcpy(skb->data, (void *)hdr + NL_MMAP_HDRLEN, hdr->nm_len); netlink_set_status(hdr, NL_MMAP_STATUS_UNUSED); - Example code path requiring a smp_wmb(): hdr->nm_uid = from_kuid(sk_user_ns(sk), NETLINK_CB(skb).creds.uid); hdr->nm_gid = from_kgid(sk_user_ns(sk), NETLINK_CB(skb).creds.gid); netlink_frame_flush_dcache(hdr); netlink_set_status(hdr, NL_MMAP_STATUS_VALID); Fixes: f9c228 ("netlink: implement memory mapped recvmsg()") Reported-by:

Checking the file f_count and the nlk->mapped count is not completely sufficient to prevent the mmap'd area contents from changing from under us during netlink mmap sendmsg() operations.

Pull user namespace related fixes from Eric Biederman: "As these are bug fixes almost all of thes changes are marked for backporting to stable. The first change (implicitly adding MNT_NODEV on remount) addresses a regression that was created when security issues with unprivileged remount were closed. I go on to update the remount test to make it easy to detect if this issue reoccurs. Then there are a handful of mount and umount related fixes. Then half of the changes deal with the a recently discovered design bug in the permission checks of gid_map. Unix since the beginning has allowed setting group permissions on files to less than the user and other permissions (aka ---rwx---rwx). As the unix permission checks stop as soon as a group matches, and setgroups allows setting groups that can not later be dropped, results in a situtation where it is possible to legitimately use a group to assign fewer privileges to a process. Which means dropping a group can increase a processes privileges. The fix I have adopted is that gid_map is now no longer writable without privilege unless the new file /proc/self/setgroups has been set to permanently disable setgroups. The bulk of user namespace using applications even the applications using applications using user namespaces without privilege remain unaffected by this change. Unfortunately this ix breaks a couple user space applications, that were relying on the problematic behavior (one of which was tools/selftests/mount/unprivileged-remount-test.c). To hopefully prevent needing a regression fix on top of my security fix I rounded folks who work with the container implementations mostly like to be affected and encouraged them to test the changes. > So far nothing broke on my libvirt-lxc test bed. :-) > Tested with openSUSE 13.2 and libvirt 1.2.9. > Tested-by: Richard Weinberger <richard@nod.at> > Tested on Fedora20 with libvirt 1.2.11, works fine. > Tested-by: Chen Hanxiao <chenhanxiao@cn.fujitsu.com> > Ok, thanks - yes, unprivileged lxc is working fine with your kernels. > Just to be sure I was testing the right thing I also tested using > my unprivileged nsexec testcases, and they failed on setgroup/setgid > as now expected, and succeeded there without your patches. > Tested-by: Serge Hallyn <serge.hallyn@ubuntu.com> > I tested this with Sandstorm.

The optimization for filtering out extended inquiry results, advertising reports or scan response data based on provided UUID list has a logic bug. In case no match is found in the advertising data, the scan response is ignored and not checked against the filter. This will lead to events being filtered wrongly. Change the code to actually only drop the events when the scan response data is not present. If it is present, it needs to be checked against the provided filter. The patch is a bit more complex than it needs to be. That is because it also fixes this compiler warning that some gcc versions produce. CC net/bluetooth/mgmt.o net/bluetooth/mgmt.c: In function ‘mgmt_device_found’: net/bluetooth/mgmt.c:7028:7: warning: ‘match’ may be used uninitialized in this function [-Wmaybe-uninitialized] bool match; ^ It seems that gcc can not clearly figure out the context of the match variable. So just change the branches for the extended inquiry response and advertising data around so that it is clear. Reported-by:

Dave Hansen reports that commit fb7332a9 ("mmu_gather: move minimal range calculations into generic code") caused a performance problem: "tlb_finish_mmu() goes up about 9x in the profiles (~0.4%->3.6%) and tlb_flush_mmu_free() takes about 3.1% of CPU time with the patch applied, but does not show up at all on the commit before" and the reason is that Will moved the test for whether we need to flush from tlb_flush_mmu() into tlb_flush_mmu_tlbonly(). But that meant that tlb_flush_mmu_free() basically lost that check. Move it back into tlb_flush_mmu() where it belongs, so that it covers both tlb_flush_mmu_tlbonly() _and_ tlb_flush_mmu_free().

Pull fuse update from Miklos Szeredi: "The first part makes sure we don't hold up umount with pending async requests. In addition to being a cleanup, this is a small behavioral change (for the better) and unlikely to break anything. The second part prepares for a cleanup of the fuse device I/O code by adding a helper for simple request submission, with some savings in line numbers already realized" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: fuse: use file_inode() in fuse_file_fallocate() fuse: introduce fuse_simple_request() helper fuse: reduce max out args fuse: hold inode instead of path after release fuse: flush requests on umount fuse: don't wake up reserved req in fuse_conn_kill()

make sure 'value' is not null. otherwise __ceph_setxattr will remove the extended attribute. Signed-off-by:

mksnap reply only contain 'target', does not contain 'dentry'. So it's wrong to use req->r_reply_info.head->is_dentry to detect traceless reply. Signed-off-by:
